Implemented standards for code quality, automated the building of container images (CI), and established a CD process using ArgoCD. This enabled the tracking, monitoring, and deployment of dozens of micro-services and their supporting infrastructure, such as databases, exchanges, vaults, and network connectivity.Improved Team Output: Achieved a significant improvement in our team’s output, transitioning from pushing container images with critical vulnerabilities and inconsistent code quality to a state where all images have no serious vulnerabilities and code quality consistently passes the company-wide quality gate.Mentorship and Training: Provided extensive mentoring and training to junior engineers, helping them quickly develop their skills and confidence.
